MEANS FOR PRODUCING A FABRIC BY COMBINED KNITTING AND WEAVING.

Application filed May 1, 1928, Serial'No. 106,175, and in Germany December 24, 1925.

This invention relates to means for producing a fabric by combined knitting and weaving, and the invention consists essentially in performing the knitting across the woven fabric at the beat-up point of the loom alternately with the beating-up so that the sewing threads will be emmeshed in the stitches.

This arrangement allows the weaving to proceed in the usual manner, and any desired patterning may be applied to the woven as well as to the knitted part of the fabric.

The invention also consists in the various details of construction and combination of machine parts as hereinafter set forth and claimed.

Fig. 1 of the accompanying drawings represents a front view of the machine whereby the invention may be carried out, and

Figs. 2 and 3 are opposite side views of the same.

The loom presents on the whole the usual appearance. The warp 2 is led from the beam 3 over the back support 4 and thence through a shedding mechanism which may be of the jacquard type so that any desired pattern may be obtained. In the drawings where the machine and the product are shown in their simplest form, two sets of spring-supported heddle eyes are operated by levers 30 (Fig. 6), and cams 31 which receive their motion from the main shaft 32 through the medium of a toothed gearing 33. The weft is supplied by a shuttle in the usual manner, the pickers 6 being operated by spring-actuated sticks 34 and helical cam faces 35 kept in motion by a shaft 36 to which rotation is imparted from the main shaft. The lay sword 9 is operated, as shown in Fig. 7, by cams which are mounted on the main shaft 32 and which cooperate with rollers 11 on appropriately disposed lever arms. The reed 7 only forwards the weft as far as the point 8 (Fig. 2). From thispoint to the end of the shed, the beatingup is effected by reed dents 12 carried by a slide 15. Thelatter is guided on a frame 37 which rocks about a shaft 38 under the influence of cams 16 mounted on a shaft 28. Curved springcontrolled arms 39 which rock about the main shaft 32, are linked to the slide and operated-by cams d0 on the shaft 28 so as to reciprocate the slide on the guideway provided for it in the frame 37.

The beat-up point 14 is situated under a stripping bar 21 which is grooved transversely to form guides for the knitting needles 13. The latter are connected to a slide 11 which is arranged in a guideway over the bar 21 so that it can be reciprocated for passing the, needles up and down through the fabric between the warp threads. The slide 11 is connected by links 12 (Figs 8) to levers which are controlled by springs 44 and rocked by the co-operation of the springs with cams 22 mounted on the main shaft 32. Rollers 23 on the lovers take the thrust of the cams. While the stripping bar 21 supports the fabric from below and strips the loops off the needles, a presser bar 26 supports the fabric from above while the needles are raised. The bar 26 is carried by arms 27 connected to a rock shaft 4:5. This rock shaft is operated by a rod which is reciprocated by an eccen tric 30 mountedon the shaft 28.

The guides for the knitting threads 18 are secured to a bar 416 which is carried by arms connected to a rock shaft 4:8. The latter is rocked by cams 19 mounted on a shaft 17 for placing the threads in the hooks of the needles 13. The shaft 48 is also capable of axial displacement and is reciprocated by the co-operation of a spring with a pattern cam 20 so as to shift the threads into engagement with different needles. There may be more than one set of thread guides controlled by different pattern cams or by dobbies or pattern change chains, in which case a much greater variety of patterns can be produced. The cam 20 may be driven by a worm wheel gear 49 which receives motion from the shaft 28 by means of a chain 50 and sprocket wheels 51.

The knitting threads 18 are supplied from a beam 18'. The finished fabric 24 is taken up by a cloth beam 25.

Figs. 15 to 18 illustrate the operation of the machine. In Fig. 15 the presser bar 26 is shown lowered so as to support the fabric while the needles 13 are raised through their loops behind the last weft thread for catching the knitting threads 18. The supplemental reed dents 12 are retracted underneath the shed. While the next weft thread 29 is being advanced by the reed 7, the thread guides 17 move so as to place the threads in the needle hooks. Fig. 16 shows the threads in the hooks; the reed 7 is retracted and the supplemental reed dents 12 are raised into engagement with the fresh weft thread. The needles 13 are now lowered so as to make new loops across the previously beaten-up weft thread, the new loops being pulled through the old ones which are stripped off the needles by the bar 21. At the same time, the presser bar 26 is raised, and the dents 12 are advanced so as to bring the new thread right up to the end of the shed. This position of the elements is shown in Fig. 17. The dents 12 are now retracted, while the presser bar 26 is lowered and the needles raised behind the new weft thread for forming fresh loops around the latter. If the thread guides have meanwhile been shifted laterally, the fresh loops will be formed by different threads so that the warp will also be engaged in the stitches. Fig. 13 shows a lain fabric emmeshed in this manner by 'nitting threads which form loops around the weft threads 29 alternately at opposite sides of the warp thread 2.
